Minecraft Realm Not Downloading/Getting Stuck

I have recently been experiencing a bug on my 2 year minecraft world that is 1.7 gigabytes. This issue has been going on for about one year now. I do not want to lose my progress and my realm has recently expired and I want to play it. Bedrock realms have many glitches, especially considering it is a premium service. I believe the minecraft developers should fix this immediately as many people are effected and losing many great worlds due to this glitch. Please fix this as soon as possible because I have about 50 people who want this glitch fixed. (It has also been getting stuck around 656 megabytes for reference)
